Wow, if somebody had alerted me to my presence on this thread, I woulda chimed in sooner!
Thanks Len, for recommending me.
I resolder all the x10 Elite PS boards - including the 532 and 642 non-Elite Pioneer HDreadys, and the x20 Elites - including the 533 and 643 non-Elite - PS boards that are vertically mounted. The final part of the x20 model year they redesigned an entirely new PS board and mounted it on the floor of the units and it has none of the cold solder joint problems of the x10 series, but for the first volley of that model year they used the old boards from the year before - the x10 series - all of which were badly soldered on the entire board. The solder flow op was incorrectly done, and years later solder joints started to go out on them right and left, eventually taking down boards downline from the PS board
These sophisticated units were never designed to be operated on hinky power supply boards, ONLY on rock solid ones. They have no defense against huge spikes being sent to them from connections that intermittently let go, in parts of the PS circuit. These spikes act like lightning bolts, damaging circuits downline. There are no surge suppressors or arc gaps to protect the rest of the set when the power supply circuit - which powers up 100% of the entire set - has gone renegade.
So if your set is experiencing any of this, STOP USING IT NOW. Don't play Russian Roulette with it.
:nono:
Send it to me, or in a pinch to Len. We will resolder it to within an inch of its life. On all pertinent connections, not just the ones that are bad now, which is what most local repair personnel do. We resolder 99% of that board, with the only exceptions to that being test points, heat sinks and anything that's already been redone on the board during original production, AFTER their botched solder flow op. Nothing less will do.
Once your set is working properly again, be in touch with me about further enhancements, which can deliver stunning HD to your present CRT set. It all starts with optics cleaning, which is ABSOLUTELY ESSENTIAL on CRT tech. That 30KV really does a number on your optics. 10 surfaces get trashed! You wanna know why your set looks bleary? It's NOT AGE! It's the optics. That's all! The static cling from the 30KV literally causes ALL airborn particulates to be sucked out of the air and onto your optics every minute the set is on. See my website for more information.
Your set is NOT old, even at this age. CRT just keeps going, and going, and going...
